The number of meter (m) in 1 cubit, given the data is 4.25×10⁵ m

<h3>Data obtained from the question</h3>

From the question given above, the following data were obtained:

  • 50 trillion (5.00 x 1013) Angstrom = 10900 cubit
  • 108 Angstrom = 1 cm
  • How many meter (m) = 1 cubit?

<h3>How to convert 5×10¹³ Angstrom to cm</h3>

108 Angstrom = 1 cm

Therefore,

5×10¹³ Angstrom = 5×10¹³ / 108

5×10¹³ Angstrom = 4.63×10¹¹ cm

<h3>How to convert 1 cubit to cm</h3>

10900 cubit = 5×10¹³ Angstrom = 4.63×10¹¹ cm

10900 cubit = 4.63×10¹¹ cm

Therefore,

1 cubit = 4.63×10¹¹ / 10900

1 cubit = 4.25×10⁷ cm

<h3>How to convert 4.25×10⁷ cm to m</h3>

100 cm = 1 m

Therefore,

4.25×10⁷ cm = 4.25×10⁷/ 100

4.25×10⁷ cm = 4.25×10⁵ m

Thus,

1 cubit = 4.25×10⁷ cm = 4.25×10⁵ m

1 cubit = 4.25×10⁵ m

gThe mole fraction of potassium nitrate in an aqueous solution is 0.0194. The solution's density is 1.0627 g/mL. What is the mol
xxMikexx [17]

Answer:

0.595 M

Explanation:

The number of moles of water in 1L = 1000g/18g/mol = 55.6 moles of water.

Mole fraction = number of moles of KNO3/number of moles of KNO3 + number of moles of water

0.0194 = x/x + 55.6

0.0194(x + 55.6) = x

0.0194x + 1.08 = x

x - 0.0194x = 1.08

0.9806x= 1.08

x= 1.08/0.9806

x= 1.1 moles of KNO3

Mole fraction of water= 55.6/1.1 + 55.6 = 0.981

If

xA= mole fraction of solvent

xB= mole fraction of solute

nA= number of moles of solvent

nB = number of moles of solute

MA= molar mass of solvent

MB = molar mass of solute

d= density of solution

Molarity = xBd × 1000/xAMA ×xBMB

Molarity= 0.0194 × 1.0627 × 1000/0.981 × 18 × 0.0194×101

Molarity= 20.6/34.6

Molarity of KNO3= 0.595 M

Check all items common to bases.<br> minerals<br> metal<br> gas<br> H+<br> OH-<br> nitrogen
Darya [45]

OH- is common to bases.

Explanation:

The base is a is an ionic compounds which when placed in aqueous solution dissociates in to a cation and an anion OH-.

The presence of OH- in the solution shows that the solution is basic or alkaline.

From Bronsted and Lowry concept base is a molecule that accepts a proton for example in NaOH, Na is a proton donor and OH is the proton acceptor.

A base accepts hydrogen ion and the concentration of OH is always higher in base.

There is a presence of conjugate acid and conjugate base in the Bronsted and Lowry acid and base.

Conjugate acid is one which is formed when a base gained a proton.

Conjugate base is one which is formed when an acid looses a proton.

And from the Arrhenius base Theory, the base is one that dissociates in to water as OH-.
